Sue,

I looked up the HE coma and found this "Hepatic encephalopathy" With Killian in coma, it does look bad indeed.

I truly wish & pray with all my might that Killian would be able to
recover from this.My heart aches for you both. If it be God's
will that Killian come to Rainbow Bridge, I hope his passing is
peaceful & pain free. Tender kisses for that sweet boy.

{{{HUGS}}} Liz.
